git-findtags
fetches is a descendant of `<lbranch>`. This option
overrides that check.
+\--no-tags::
+ By default, `git-fetch` fetches tags that point at
+ objects that are downloaded from the remote repository
+ and stores them locally. This option disables this
+ automatic tag following.
+
-t, \--tags::
- By default, the git core utilities will not fetch and store
- tags under the same name as the remote repository; ask it
- to do so using `--tags`. Using this option will bound the
- list of objects pulled to the remote tags. Commits in branches
- beyond the tags will be ignored.
+ Most of the tags are fetched automatically as branch
+ heads are downloaded, but tags that do not point at
+ objects reachable from the branch heads that are being
+ tracked will not be fetched by this mechanism. This
+ flag lets all tags and their associated objects be
+ downloaded.
-u, \--update-head-ok::
By default `git-fetch` refuses to update the head which
corresponds to the current branch. This flag disables the
check. Note that fetching into the current branch will not
update the index and working directory, so use it with care.

DESCRIPTION
-n::
No checkout of HEAD is performed after the clone is complete.
+-o <name>::
+ Instead of using the branch name 'origin' to keep track
+ of the upstream repository, use <name> instead. Note
+ that the shorthand name stored in `remotes/origin` is
+ not affected, but the local branch name to pull the
+ remote `master` branch into is.

DESCRIPTION
-----------
git-daemon will refuse to start when this option is enabled and no
whitelist is specified.
+--base-path::
+ Remap all the path requests as relative to the given path.
+ This is sort of "GIT root" - if you run git-daemon with
+ '--base-path=/srv/git' on example.com, then if you later try to pull
+ 'git://example.com/hello.git', `git-daemon` will interpret the path
+ as '/srv/git/hello.git'. Home directories (the '~login' notation)
+ access is disabled.
+
--export-all::
Allow pulling from all directories that look like GIT repositories
(have the 'objects' and 'refs' subdirectories), even if they

+NAME
+----
+git-describe - Show the most recent tag that is reachable from a commit.
+
+
+SYNOPSIS
+--------
+'git-describe' [--all] [--tags] [--abbrev=<n>] <committish>...
+
+DESCRIPTION
+-----------
+The command finds the most recent tag that is reachable from a
+commit, and if the commit itself is pointed at by the tag, shows
+the tag. Otherwise, it suffixes the tag name with abbreviated
+object name of the commit.
+
+
+OPTIONS
+-------
+<committish>::
+ The object name of the comittish.
+
+--all::
+ Instead of using only the annotated tags, use any ref
+ found in `.git/refs/`.
+
+--tags::
+ Instead of using only the annotated tags, use any tag
+ found in `.git/refs/tags`.
+
+--abbrev=<n>::
+ Instead of using the default 8 hexadecimal digits as the
+ abbreviated object name, use <n> digits.
+
+
+EXAMPLES
+--------
+
+With something like git.git current tree, I get:
+
+ [torvalds@g5 git]$ git-describe parent
+ v1.0.4-g2414721b
+
+i.e. the current head of my "parent" branch is based on v1.0.4,
+but since it has a few commits on top of that, it has added the
+git hash of the thing to the end: "-g" + 8-char shorthand for
+the commit `2414721b194453f058079d897d13c4e377f92dc6`.
+
+Doing a "git-describe" on a tag-name will just show the tag name:
+
+ [torvalds@g5 git]$ git-describe v1.0.4
+ v1.0.4
+
+With --all, the command can use branch heads as references, so
+the output shows the reference path as well:
+
+ [torvalds@g5 git]$ git describe --all --abbrev=4 v1.0.5^2
+ tags/v1.0.0-g975b
+
+ [torvalds@g5 git]$ git describe --all HEAD^
+ heads/lt/describe-g975b

+ When the command is invoked from a subdirectory, show the
path of the current directory relative to the top-level
directory.
+--show-cdup::
+ When the command is invoked from a subdirectory, show the

+
--since=datestring, --after=datestring::
Parses the date string, and outputs corresponding
--max-age= parameter for git-rev-list command.
gitlink:git-cat-file[1]::
Provide content or type/size information for repository objects.
+gitlink:git-describe[1]::
+ Show the most recent tag that is reachable from a commit.
+
gitlink:git-diff-index[1]::
Compares content and mode of blobs between the index and repository.
and put them in the same group. Make sure that the repository
shared among these developers is writable by that group.
+. Initializing the shared repository with `git-init-db --shared`
+helps somewhat.
+
+. Run the following in the shared repository:
++
+------------
+$ chgrp -R $group repo.git
+$ find repo.git -type d -print | xargs chmod ug+rwx,g+s
+$ GIT_DIR=repo.git git repo-config core.sharedrepository true
+------------
+
+The above measures make sure that directories lazily created in
+`$GIT_DIR` are writable by group members. You, as the
+repository administrator, are still responsible to make sure
+your developers belong to that shared repository group and set
+their umask to a value no stricter than 027 (i.e. at least allow
+reading and searching by group members).
+
You can implement finer grained branch policies using update
hooks. There is a document ("control access to branches") in
Documentation/howto by Carl Baldwin and JC outlining how to (1)
